Nope. Biochemical calculation doesn't care about carbohydrates, fats, proteins, or Big Macs.
Creation of more and more fat cells is a function of calories in vs. calories out, and nothing else.
Some types of food force you to consume more calories in order to feel satisfied, and some
foods are so pleasant to eat they persuade you to consume more calories.
Medicine that causes lethargic behavior slows metabolism, so may reduce calories burned in normal
life, requiring special effort to get enough exercise or a reduction in caloric intake.
But it still boils down to simply calories in vs. calories out, and a biochemist can demonstrate that
mathematically.
Then why do diabetics need a special diet? To a certain extent it is calories in calories out but different foods convert to fuel more quickly than others. High glycemic foods convert to glucose (sugar) more quickly, causing blood sugar to spike. Insulin (which is only present when there's too much glucose in the body) gets rid of excess sugar. It does this by causing the cells to absorb the excess. Unfortunately, it also causes extra fatty acids to be stored in fat cells. The slower digestion, the slower food is converted to energy so it's released at a steadier pace rather than all at once. Some people's bodies are more efficient than others.
